运行写的不太完善的爬虫程序, 未限制任务队列大小, 再加上本子配置不高, 爬取网站到第3层大半时, 内存不足了...
进程运行太猛, 导致系统 out of memory, 那么此进程被系统的oom killer杀死.
此时终端显示 "Killed" 或 "已杀死".
查看相关信息的命令:
dmesg | egrep -i -B100 'killed process'
或:
egrep -i 'killed process' /var/log/messages
egrep -i -r 'killed process' /var/log
或:
journalctl -xb | egrep -i 'killed process'
结果类似这样:
4月 07 10:48:58 arch kernel: Out of memory: Kill process 1245 (python) score 685 or sacrifice child
4月 07 10:48:58 arch kernel: Killed process 1245 (python) total-vm:3519016kB, anon-rss:2453976kB, file-rss:0kB
